Hi, I am after a bit of advice/assistance as I am a bit weak on the hardware side of things and I am not 100% sure if I can achieve what I am after with the ChipWhisperer.
I have a chip that has several security features built into it that mean that it will erase the stored keys if it detects tampering such as attempts to remove the chip. Due to the location of the board I am unable to access the power or clock pins and I can not input my own data. I may be able to access the output but I am ideally trying to show that regardless of the current security features that the implementation is vulnerable to a em/tempest attack and that it can be conducted it in such a way so it wouldn’t be obvious that an attack had even occurred.
I was wondering if the H-probe, ChipWhisperer and software are sufficient or if this can only work if it is matched with another source of data such as the output? I am trying to show that just the H-probe and some processing is all that is required to reveal the key.
I control the software/programming for the keys but the hardware is not manufactured by my company. I am trying to demonstrate that things are not as secure as my boss believes.
